Abstract—Management of municipal solid waste in Indonesia is majority disposed to landfill. The are some problem on landfill in Yogyakarta namely are scavenger, cattle cow and leachate generation. The characteristics of landfill leachate generation will occur dynamically depending on the various factors including: precipitation (rainfall), evapotranspiration, water content of waste, density, field capacity, waste composition, age of waste in the landfill. This research aims to identify the characteristics of leachate generation from landfills by simulation of landfill. It was conducted by two lysimeter with 2.4 m high and 0.7 m diameter. The refuse were used as samples taken from the Piyungan landfill, Bantul regency, Special Province of Yogyakarta. Characteristic of Leachate is expressed by BOD, COD, TDS parameters. The results showed that the characteristics decay of the leachate generation from landfill with recirculated faster than without recirculated. The mathematical equations of exponential form to describe the characteristics pattern of leachate with BOD, COD and TDS parameters. Peak concentration for BOD = 7118.8 mg/L and 7411 mg/L, COD = 11232 mg/L and 1184 mg/L, TDS = 3920.9 mg/L and 4443.1 mg/L lysimeter-1 and lysimeter-2 respectively. Validation was performed using statistical criteria of goodness of fit Chi-Square with a confidence level of 0.1 shown still meet Chi-Square standards.

Index Terms—Municipal solid waste, landfill, leachate characteristic, decay pattern.
